(Why am i coming up with so much theorys)

Theory for Arceus (Very Basic)

Before the final battle with Cypress, your necklace will glow and Arceus somehow appears, after doing all the things you've done, Arceus battles with you and you are required to catch it, if it dies, you can catch it again, if your team dies, you'll just come back to what ever location Arceus was at and it'll appear again
